To all whom t may concern.'

Be it known that I, FRANCIS Cr. CAMERON,

` a subject of the King of Great Britain, re-

' attained by the device illustrated yin the aesiding at Hamilton, inthe county of Wentworth and Province of Cntario, Canada, have invented anew and useful Starch- Printing Device, of which the following ispurpose of effecting corresponding molds in y the starch. l

My invention has for its obJects, to provide a device for moreeffectively .and elfi-l ciently accomplishing this heretofore specifiedprocess in the manufacture of candy, in a substantial reduction of thetime which was hitherto required for the same.

This object, together .with other objects apparent to those skilled inthe art, may be companying drawing, in Whichz- Figure 1 is a frontelevation of the entire device, Fig. 2 is a side elevation of the samewith the tray and table removed, Fig. 3 is an enlarged detailed sideView'of the hammer operating mechanism, on the line X-X in Fig. 1', andFig. 4 is an enlarged detailed frontview of the same.

-Similar characters of reference referto Similar parts throughout theseveral views. Reference being had to the accompanying drawing,thecorner legs A, the longitudinal pieces B and C, together with twosimilarpieces which are behind the pieces B and C and therefore 'notseen in the' drawing, and the transverse pieces D, E and F, with similarpieces at the opposite side of the device, constitute the framework ofthe machine.

lhe usual tra-y2 of starch is positioned on a levelingl device which-comprises a horizontal table 3 supported by hand screws 4 which arethreaded through the'pieces B, and adapted to adjust the sald table toai level position inthe frame. VP5`is the press secured at each end to atraveler 6 adaptedlto vertically operate be-V v te tween the posts A asillustrated m Fig, 2

of the drawing, by the means hereinafter to be set forth. The saidtravelers are provided with wheels 7 adapted to engage with the saidposts, and therefore facilitate the sliding of the same.

A molding board 9 is fixed to the press `5, at 1'0 in Fig. 1 of thedrawing, -and is pro- 'vided with a multiplicity of teats 12. A

number of these molding boards areto'be provided, having various shapedteats, depending upon the shape of the candy required, each said boardto be fixed to the press, as desired. v

A' longitudinalshaft 13 is suitably jour.-

' naled at itsends to bearings 14 on the trans- -verse pieces D at eachside of the machine,

and has rigidly secured toits central part,

a lever 15. Quadrant gears 16 are rigidly secured to each end of theshaft v1,3, and are adapted tomesh with corresponding vertical racks 17,which are rigidly secured tothe top of the press 5.

The racks 17 .are adapted to travel vertically in suitable guide tracks18 secured to the top of the transverse pieces D, and it will be seenthat motion` delivered to the lever 15 in the fdirection indicated bythe arrow,-will -cause the press V5, together with the molding board 9,to descend and to effeet molds, corresponding to the teats 12, in theAstarch in the tray- 2. I

Counter weights 1 9 are secured to .integral :arms 20 radially extendingfrom the respective quadrant gears'l, 'as-shown in Fig. 2 of thedrawing, for the purpose of automatically returningthe press 5 to itsprevious position after it hasperformed its function.

which becomes pulverized byv the impact of A silk screen 22 is providedbetween the molding board 5 and the teats 12,v for the the moldingboard. The said starch per- 10U forates through said screen and risesthrough,l a plurality 'of apertures or slots 21 in the' molding board 5,leaving perfectly, smooth lthe surface of the starch in thetray 2.

-An apparatus for jarringor agitating the press and molding board, whiledescending,

in order to relieve it from starch vwhich possibly adheres to it fromits last. operation, is provided as follows: l A

A cani 23 is rigidly secured to the shaft 13 llllil in proximity to thelever l5,.and is provided witha plurality of teeth 24, pivotallyconnected thereto inrespective slots. 25 is a paWl rigidly secured, inalinement With the cam 23, to one end of a shaft 26, which shaft isjournaled in bearings 27 lon a bracket 28. A

hammer 29 is'rigidly'secured to the opposite endl of the shaft 26, andis adapted to move simultaneously With the pa.\'vl 25. The said hammeris tensioned against the top of the press 5 by means of spiral spring 30fixed 4 around'the shaft 26 between the bearings 27.

`the teeth' 2l While passing the pawl 25, move to the upper limits oftheir respective slots, and therefore effect no agitation to the press,leaving the tray of molded starch with a smooth surface.

A hopper 31 is positioned in the frame,

l' below the table 2; in order to receive and to preserve the Wastestarchfrom the'different tra s, and 32 is a clean-out or eXit'for thesai starch from the hopper.

' 1. In a starch printing device, a frame, a

'table mounted in the `frame and adapted to support a tray of starch, avertically operaytive press in the frame above said table, .a moldingboard fixed to the underside of said press and having a plurality ofapertures or slots therein, a silk screen, on the under side of saidmolding board, a plurality of molding teats fixed to the under side vofsaid molding board, vertical racks secured to the top of said press,guide means for said racks, a longitudinal, horizontal shaft journaledatits ends to the top of Aeach side of the frame; quadrant gears rigidlysecured-to said shaft and adapted to mesh with said racks on the press,a. lever rigidly secured to the central part of sa-id shaft, means forcounterbalancing said press and molding board, and automatic means foreffecting ]ars or agitation to the press and molding board While it isdescending.

2. In a starch printing device, a frame, a table mounted in the frameand adapted to support a tray of starch., a vertically operative pressin said frame above said table, a molding board fixed to the under sideof said press, a plurality' of molding teats on the bottom of saidmolding board, vertical racks secured 'to the top of said press, ahorizontal shaft j ou-rnaled atjits ends to bearings on the top of eachside of the frame, quad-l rant gears rigidly secured to Said shaft andadapted to mesh with said racks on the press, a lever rigidly secured tothe central part of said shaft, means for counter balancing said pressand molding'board, a cam rigidly secured to said shaft, a plurality ofteeth pivotally connected in respective slots to said cam, -a shaftjournaled in bearings on av bracket secured -to the rear top part of theframe, a pawl rigidly secured to one end of said shaft and adapted toabut against said teeth, a hammer rigidly secured to the opposite end ofsaid shaft and adapted to operate simultaneously with said paWl, and aspiral springaround said shaft between said bearings for the purpose oftensioning said hammer against thetop of the press, for the purposespecified.
